Unanswered: Loosing ODBC connection

Hi all,

We recently converted an application from accecc97 to access2003.
We used to have 2 databases : 1 with all and only the data (axelD.mbd), 1 with all the forms, query's, ... (axelP.mdb)

We replaced the data (axelD.mdb) with an MSDE database, through UPSIZE and so on. That all worked fine.
This database is placed on the dataserver (DATA1), the converted programm is on the FRONT2 server (FRONT1 stil usess access97 until conversion is totally ready).

We are able to connect to the MSDE by using ADODB recordsets.
We are also perfect able to link the MSDEtables in our axelP.mbd database

We started to test some heavier parts of our application and started to get the following error:

"ERROR 3151"
"ODBC--connection to 'JOROSOFT' failed"

Nothing more.

This happened in a quite complex routine, whitch updates a lot of records, several times and so on.
We could reproduce the same error when executing the following code:

I know this code makes no sence in a real-time environment, but it was to reproduce the error.
This code basically runs trough a 30.000 records and does a little check for certain fields
After 1981 records we get the above error.
(sometimes after 1979 or 1980 or 1982 records)

If one brings so much courage to this world the world has to kill them or break them, so of course it kills them. The world breaks every one and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry. Earnest Hemingway, A Farewell To Arms.

Is there no one around who recognises the problem or came across that problem?

I've tried playing with the Query governor, but that didn't changed a single thing.

The strange thing is that when i try the same code on a identically server that is in use by users, i have it less frequent.
It looks like the MSDE server cant keep up with all the quesry's executed. And when the server has more users working, it has enough time to release some things.
